	     <description descriptionType="Abstract">The IPOC seismic network is part of the Integrated Plate boundary Observatory Chile (IPOC), a European-Chilean network of institutions and scientists organizing and operating a distributed system of instruments and projects dedicated to the study of earthquakes and deformation at the continental margin of Chile. In particular, the seismic network is jointly operated by the GFZ German Research Centre for Geosciences, Potsdam, Germany; the Institut de Physique du Globe Paris, France (IPGP); the Chilean National Seismological Centre (CSN); the Universidad de Chile, Santiago, Chile (UdC); and the Universidad Católica del Norte, Antofagasta, Chile (UCNA). The subduction plate boundary between the South American and the oceanic Nazca plates exhibits some of the largest earthquakes on Earth. The IPOC goal is to improve the understanding of both the physical mechanisms underlying these processes and the natural hazards induced by them. The observatory is designed to monitor the plate boundary system from the Peru-Chile border to south of the city of Antofagasta, from the coast to the high Andes, capturing both great and small earthquakes in this region. A key component of IPOC is its multi-parameter observatories, where at each site a suite of different physical parameters are measured continuously. So far about 20 such multi-parameter stations are installed. All of these sites are equipped with STS-2 broadband seismometers and accelerometers. Additional instrumentation at some of the stations includes continuous GPS, electric and magnetic field (MT), surface inclination, and climate (temperature, air pressure, humidity). Most sites transmit their data in near-real time using a suite of communication channels (VSAT, WiFi, telemetry etc.). Seismic instruments are deployed on concrete pedestals in bedrock caverns (a few meters deep) to measure ground shaking from earthquakes or other sources that last from a tiny fraction of a second to several hours. Strong-motion sensors are deployed next to the broadband sensors to increase the dynamic range and for earthquake engineering applications. Broadband data are freely distributed in real-time and archive data is also available. This DOI encompasses all IPOC seismic data; data is available under FDSN network code CX.</description>
